Christie's is honored to be the auction house to offer a one-of-a-kind watch created by Patek Philippe explicitly for the Children Action auction of October 15, 2018. This is the first and only titanium version of the Ref. 5524 Calatrava Pilot Travel Time.

The titanium case has a black dial that is manually executed with a vertical satin finish. It comes on a vintage black calfskin strap with contrast stitching. The sapphire-crystal case back exposes the automatic Patek caliber 324 S C FUS and bears the inscription "Children Action 2018".

This unique timepiece will be on display during their Geneva Rare Watches preview on May 11th thru the 13th.
